1. What Are Emotions? Emotion is defined as a subjective mental state that is usually accompanied by distinctive behaviors as well as involuntary physiological changes. Three aspects of emotions: 1. Feelings 2. Actions 3. Physiological arousal Emotional states are caused by the autonomic nervous system: 1.The sympathetic nervous system (the “fight or flight” system that generally activates the body for action) or 2.the parasympathetic nervous system (which generally prepares the body to relax and recuperate).

4. Cognition Plays a Role in the Experience of Emotion Schachter’s cognitive attribution model, emotional labels (e.g., anger, fear, joy) are attributed to relatively nonspecific feelings of physiological arousal. Our emotional experience results from cognitive analysis of the context around us.

5. Cognition Plays a Role in the Experience of Emotion Our emotional experience results from cognitive analysis of the context around us. Emotional experiences of subjects unknowingly injected with epinephrine could vary depending on how the people around them were acting.

6. Emotions from the Evolutionary Viewpoint Darwin suggested that expressions and emotions came from a common ancestor. Besides expressions, he noted the similarity in facial musculature and nerves in human and nonhuman primates.

Language as context for the perception of emotion Lisa Feldman Barrett, Kristen A. Lindquist, and Maria Gendron Trends Cogn Sci. 2007 August; 11(8): 327–332.

32. Context Effects on Emotion Perception Context such as visual scenes, voices, bodies, other faces, cultural orientation, and even words Influences on perception of facial expression of emotions –by descriptions of the social situation –scowling faces are more likely to be perceived as fearful when paired with the description of danger –Faces portraying disgust are perceived as proud when paired with a muscled body whose arms are raised in triumph Cultural context influence how perceivers sample information from a face fixate around the eyes, nose, and mouth vs primarily on the eyes

33. Context in Emotion Perception Social Context influence on emotions Expectation in the context of relationships, whether or not the expected outcome for a certain event takes place –For example forgetting a birthday Significant Social situations create emotional responses –Social demands –Personal gratification –Cultural influences Dysfunctional relationships produce a wide range of negative emotions such as anger, anxiety, and depression Functional relationships can buffer and protect people against various life stressors and create positive affective states A strong correlation between expression of emotions and relationship satisfaction
